WebFc regions of many antibodies readily bind to the Fc-receptors at different levels. Most commercially available antibodies contain Fc segments. To eliminate this problem, one can use an Fc blocking reagent, which contains a recombinant protein derived from immunoglobulin that will bind to the Fc-receptors and minimize the non-specific binding. WebFeb 19, 2024 · The antibody might be expressed in the membrane of a B cell, bind to a mast cell by its Fc region, or be phagocytosed after opsonization, or cause complement fixation, all with different effects. But note a cell that engulfs unbound antibody cannot present the antigen it didn't bind to. :) – Mike Serfas Feb 19, 2024 at 2:32 dahl funeral chapel of bozeman inc - bozeman
